Hi and thank you for the proposals!
I like the 1 in the negative space as an idea, #158, #159 and #160 being the ones that I like the most...
#152, #153, #156, #157 are well executed but I don't feel them strong enough, as I don't like that much the clock, the calendar, the bordered lettering.
Could you further elaborate on the negative one idea and eventually propose completely different concepts?
Again thank you!
Dario
